Casino Diria Tamarindo

The only place in Tamarindo to play blackjack, Carribean Stud, no-limit Texas Hold'em and electronic roulette is at Casino Diria, located in the heart of Guanacaste's favorite party town.
Linked to the Diria Beach Resort and Hotel, the casino offers supreme service and a classy atmosphere, and besides the card tables you can take your chances at any of the 48 slot machines here. Meanwhile, you're never more than just a few steps from the lounge-style bar that serves cool cocktails, beer and wine, where you can sit and watch people pass by on the street below as you take a break.
The casino accepts U.S. dollars as well as the local currency, Colones, so there's no need to exchange money once you arrive. But don't worry, there are several banks and ATMs nearby just in case.
Also under the same umbrella as the Diria Casino and Hotel are an excellent pizza restaurant called Nari, boasting a wood-fired oven, the Flying Bull which serves steaks and international cuisine, and Ta.Paz Bar & Grill, serving tapas in the same building as the casino.
